In Finland, Ascension Day, known as 'Helatorstai' in Finnish, is a public holiday. It is celebrated 40 days after Easter, marking the biblical event when Jesus Christ ascended to heaven following his resurrection. Like in many other Christian countries, this day has significant religious importance in Finland and is marked by special church services and processions.

Apart from its religious significance, Ascension Day in Finland also marks the start of the summer season. This is reflected in the traditional festivities which often include outdoor activities and events. Many Finns also take advantage of the long weekend, as Ascension Day falls on a Thursday, to take short vacations or to visit their summer cottages in the countryside. This is also the time when many businesses open their summer season.

Given the public holiday status, schools, banks and most businesses are closed on Ascension Day, with only essential services running on reduced hours. The day is also a popular time for confirmations and weddings in the Lutheran Church of which a sizable percentage of Finns are members. Over the years, while the religious significance may have diminished for some, the importance of Ascension Day as a time for families to come together and celebrate the arrival of summer remains strong.
